Which arrangement carries the drive to the rear wheels in a front engine car?

  • A.A propeller shaft with universal joints
  • B.A pair of driveshafts running directly from the gearbox to each of the rear wheels independently of one another
  • C.A chain drive
  • D.A hydraulic transmission, in which a pump at the engine drives motors mounted within each of the rear wheel hubs

Answer: A

The propeller shaft runs from the gearbox to the final drive, with universal joints at each end to accommodate the angular movement as the axle rises and falls. A sliding spline accommodates the change in length. Long shafts are divided into two sections with a centre bearing to avoid whirling at high speed.
